    Common Blood Tests

    Doctors use information obtained from Laboratory analysis to diagnose or predict disease, and to monitor various therapies for effectiveness. Blood is complex mixture of chemicals, hormones, proteins, and cellular elements. Any imbalance, or too much or too little of specific constituents, can indicate the nature of certain disorders. There are thousands of components that can be analyzed with just a tube or two of blood.

    Electrolytes: Salts which break down in the body are transported in the blood as the charged particles, Sodium, Potassium, Chloride, and Bicarbonate. These Electrolytes are maintained in health within tightly-controlled ranges – too much deviation from normal can be critical. Electrolytes are commonly measured as indicators for metabolic functioning, acid-base balance, renal or lung disease, or as a general measure of nutrition and hydration.

    Basic Metabolic Panel (BMP): BMP is commonly included as part of general health profile and includes Electrolytes and four other constituents (Glucose, Bun, Creatinine, and Calcium) that are good indicators for kidney function, and screening for diabetes.

    Comprehensive Metabolic Panel (CMP): CMP adds more tests to the BMP to provide a broader profile. Addition of Total Protein, Albumin, Alkaline Phosphatase, ALT, AST, and Total Bilirubin provide more information on Kidneys, Liver, Lungs, and Bone.

    Lipid Panel: Used to evaluate relative risks for developing atherosclerosis or heart disease. Cholesterol, HDL, LDL, and Triglycerides are all different types of fat that are measured.

    Complete Blood Count (CBC): Measures the specific cellular elements transported in blood. Red Blood Cells (RBC), White Blood Cells (WBC), and Platelet levels can indicate anemia, infection, or leukemia. Non-specific inflammation or dehydration, along with secondary affects from many other organ disorders can all be apparent in Cell counts. A handful of specific sub-types of WBC can also be enumerated by Microscopy during a Differential analysis to try and categorized specific abnormalities.

    Prothrombin (PT): Common measurement used to monitor anticoagulation therapy when taking Coumadin to “thin” the blood. INR measures the degree of anticoagulation and allows predication for possible dosage change.

    Therapeutic Drug Monitoring (TDM): Used to quantify blood levels of many different drugs. Measurement prevents toxicity and ensures proper therapy. Some drugs commonly measured include heart medications such as Digoxin, anticonvulsants such as Dilantin, and antibiotics such as Vancomycin.

    Thyroid Tests: TSH (Thyroid Stimulating Hormone), and FT4 (Free Thyroxin) measure both the level of hormone production and relative health of the thyroid gland.
